Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 16 years and older
  • All sexes
  • No healthy volunteers
  • Child, Adult, Older adult

Who may be able to join

  • Histologically confirmed histiocytic disorder or histologic findings compatible with a histiocytic disorder in the context of confirmatory radiologic findings confirmed by the enrolling institution.
  • One of the following:
  • Documentation of BRAF V600E mutation and inability to access of BRAF inhibitor or prior treatment with a BRAF inhibitor discontinued due intolerable side effects or toxicity prior to progression, -OR-

  • Histiocytic disorder must be (a) multi-system disease or (b) disease that is recurrent or refractory to standard therapies, or (c) single-system disease with that is unlikely to benefit from conventional and less toxic therapies, based on the best available evidence (for example, CNS or cardiac infiltration, retroperitoneal fibrosis, prior chemotherapy, or other medical history or co-morbidities, etc)
  • Life expectancy > 12 weeks
  • Age ≥ 16 years
  • ECOG performance status ≤ 3 (May be converted from Karnofsky Performance Status)
  • Adequate bone marrow function as indicated by the following:
  • ANC > 1000/uL
  • Platelets ≥ 50,000/uL
  • Hemoglobin ≥ 8.5 g/dL.
  • Patients with cytopenias below these thresholds deemed to be the result of disease will be considered eligible.
  • Adequate renal function, as indicated by:
  • creatinine ≤ 1.5 the upper limit of normal (ULN) -OR-
  • Estimated creatinine clearance of > 50 ml/min
  • As for #7, patients with renal dysfunction deemed to be the result of disease will be considered eligible.
  • Adequate liver function, as defined by bilirubin ≤ 1.5 ULN
  • AND AST/ALT < 3 ULN
  • Ability to swallow pills
  • Negative serum pregnancy test within 7 days prior to commencement of dosing in premenopausal women. Women of non-childbearing potential may be included without serum pregnancy test if they are either surgically sterile or have been postmenopausal for ≥ 1 year.
  • Fertile men and women must use an effective method of contraception during treatment and for at least 6 months after completion of treatment as directed by their physician. Effective methods of contraception are defined as those which result in a low failure rate (i.e., less than 1% per year) when used consistently and correctly (for example implants, injectables, combined oral contraception or intra-uterine devices). At the discretion of the Investigator, acceptable methods of contraception may include total abstinence in cases where the lifestyle of the patient ensures compliance. (Periodic abstinence [e.g., calendar, ovulation, symptothermal, post-ovulation methods] and withdrawal are not acceptable methods of contraception.)
  • Patients must be willing to consent for protocol #12-245 for IMPACT testing (for MSK patients ONLY).

Who cannot join

Show all 19Show fewer
  • History of or evidence of retinal pathology on ophthalmologic examination that is considered a risk factor for neurosensory retinal detachment, RVO, or neovascular macular degeneration
  • The risk factors for RVO are listed below. Exclusion should be considered by clinical discretion if they have the following conditions:
  • Uncontrolled glaucoma with intra-ocular pressures > 21mmHg
  • Serum cholesterol ≥ Grade 2
  • Hypertriglyceridemia ≥ Grade 2
  • Hyperglycemia ≥ Grade 2
  • History of clinically significant cardiac dysfunction, unless deemed to be the direct result of disease, including the following:
  • Current unstable angina
  • Symptomatic congestive heart failure of NYHA class 2 or higher
  • Uncontrolled hypertension ≥ Grade 2 (patients with a history hypertension controlled with anti-hypertensives to ≤ Grade 2 are eligible).
  • Left ventricular ejection fraction (LVEF) below institutional lower limit of normal or below 50%
  • Uncontrolled arrhythmias
  • Myocardial infarction, severe/unstable angina, symptomatic congestive heart failure, cerebrovascular accident or transient ischemic attack within the previous 6 months

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • CobimetinibDrug

    Cobimetinib will be administered at a dose of 60mg daily for 21 days on, then 7 days off, in a 28 day treatment cycle. Patients will have the option to discontinue treatment after 12 cycles and will be monitored for disease relapse for an additional 12 months. In the event that disease relapse occurs within the 12 month monitoring period, patients will restart treatment and continue on study. Upon restarting, the assessment schedule will restart at rechallenge cycle 1(RC-1) and all assessments will occur at the frequency and intervals. Cycle 1 Day 15 visits will not be required for patients that restart treatment after relapse. Participants will re-sign consent upon rechallenging.

Study groups in NCT02649972
Study groupRoleWhat they receive
CobimetinibExperimentalThis is an open-label, multicenter, phase II study exploring the efficacy and safety of single-agent Cobimetinib in patients with histiocytic disorders whose tumors are 1) BRAFV600 wildtype or 2) BRAFV600E mutant and are intolerant to, or unable to access, BRAF inhibitors. Visits during the treatment period are to be completed on Day 1, Day 15 (this visit can be by telephone), Day 29, and every 28 days thereafter. For patients treated on the study for six months, at the discretion of the Principal Investigator, visits can be spaced out to every 56 days (every 2 cycles instead of every cycle). After 24 cycles of treatment, if imaging demonstrates sustained stability in the opinion of the principal investigator, tumor assessments can be performed ever 1 year.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Best Overall Response

    by PET Response Criterial (PRC), with a dichotomous BOR of CR or PR versus neither of those. Assuming we use this binary endpoint of response, defined as best overall response of CR or PR versus not using the PET Response Criteria (PRC), a sample size of 18 patients provides 90% power to test the hypothesis that the response rate is promising (defined as 35% or higher) against a non-promising rate of 10% or lower.

    Measured: 1 year

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Cobimetinib in people with Histiocytic Disorders, run by Memorial Sloan Kettering Cancer Center at 2 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 25 inclusion and 19 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 18 Nov 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 18 Nov 2023). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Best Overall Response (time frame: 1 year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Nov 2023.
